binary pocket (now wrist) watch

[Ari]

You can get the schematics here (I bought the atmega preprogrammed there).
Just put LEDs in place of the binary->BCD converters shown in the schematic.

Also, mine died a while ago (maybe from static?).
Hopefully you'll have better luck with it if you make one!

another question you have the hex file for the pic that work in this squematic....... is the atmega 8??? thanks

[Ari]

no, sorry, I don't have the hex file. or a programmer to dump it with. you could try asking the shop I bought it from if they'll send it to you.

and yes, it's an atmega8. which is actually not very good for a watch like this due to the relatively high power consumption (a few ma).
something like the PIC16F84A, which only uses 0.015ma with a low frequency crystal, would probably be much better.

and I got my watch working again! turns out the reset pin was grounded, which also explains the random resets.
